This is the tunnel on a road outside Tarapoto called the Escalera. We were last here in 2006, when it was a gravel road. We were owling at 0430 when a car full of armed plain-clothed policemen pulled up . Apparently we were on the main drug route out of the interior and they suggested we continue birding adjacent to the police road-block near the tunnel.A tense moment! We never did see the owl....
